Abstract
LA INVENCION SE REFIERE A UN COJINETE MAGNETICO PARA APOYAR SIN CONTACTO UN CUERPO MOVIL, PREFERENTEMENTE ROTATORIO, DENOMINADO EN ADELANTE ROTOR, CON RESPECTO A UNA PIEZA FIJA DENOMINADA EN LO SUCESIVO ESTATOR, CON UN ENTREHIERRO COMO MINIMO ENTRE EL ROTOR Y EL ESTATOR, EN EL QUE SE HALLAN FRENTE A FRENTE, A ESCASA DISTANCIA, ZONAS MAGNETICAS DEL ROTOR Y DEL ESTATOR, DENOMINADAS IMANES DEL ROTOR Y DEL ESTATOR, RESPECTIVAMENTE. EL IMAN DEL ESTATOR PUEDE OSCILAR LIBREMENTE, BASICAMENTE EN UN PLANO PARALELO A LAS SUPERFICIES MAGNETICAS QUE SE HALLAN FRENTE A FRENTE EN LA RENDIJA ENTRE EL IMAN DEL ROTOR Y DEL ESTATOR. ENTRE EL ESTATOR Y EL IMAN DEL ESTATOR ESTA MONTADO UN DISPOSITIVO DE FRICCION MECANICA PARA AMORTIGUAR EL MOVIMIENTO OSCILANTE DEL IMAN DEL ESTATOR.
